I know that the answer to the question "Who brought their case first, Katz or Nardone?" is in "Hoover began using wiretapping in the 1920s during Prohibition to arrest bootleggers. In the 1927 case Olmstead v. United States, in which a bootlegger was caught through telephone tapping, the United States Supreme Court ruled that FBI wiretaps did not violate the Fourth Amendment as unlawful search and seizure, as long as the FBI did not break into a person's home to complete the tapping. After Prohibition's repeal, Congress passed the Communications Act of 1934, which outlawed non-consensual phone tapping, but allowed bugging. In the 1939 case Nardone v. United States, the court ruled that due to the 1934 law, evidence the FBI obtained by phone tapping was inadmissible in court. After the 1967 case Katz v. United States overturned the 1927 case that had allowed bugging, Congress passed the Omnibus Crime Control Act, allowing public authorities to tap telephones during investigations as long as they obtain a warrant beforehand.". Can you tell me what it is?
Ans: Nardone

I know that the answer to the question "What convention is followed in which a previous case has set a precedent?" is in "Federal law originates with the Constitution, which gives Congress the power to enact statutes for certain limited purposes like regulating interstate commerce. The United States Code is the official compilation and codification of the general and permanent federal statutes. Many statutes give executive branch agencies the power to create regulations, which are published in the Federal Register and codified into the Code of Federal Regulations. Regulations generally also carry the force of law under the Chevron doctrine. Many lawsuits turn on the meaning of a federal statute or regulation, and judicial interpretations of such meaning carry legal force under the principle of stare decisis.". Can you tell me what it is?
Ans: stare decisis

I know that the answer to the question "Which of the following is not a result of competition among ethnic groups: corruption, graft, or religious persecution?" is in "Ethnocentrism, tribalism, religious persecution, and prebendalism have affected Nigerian politics both prior and subsequent to independence in 1960. Kin-selective altruism has made its way into Nigerian politics, resulting in tribalist efforts to concentrate Federal power to a particular region of their interests. Nationalism has also led to active secessionist movements such as MASSOB, Nationalist movements such as Oodua Peoples Congress, Movement for the Emancipation of the Niger Delta and a civil war. Nigeria's three largest ethnic groups (Hausa, Igbo and Yoruba) have maintained historical preeminence in Nigerian politics; competition amongst these three groups has fuelled corruption and graft.". Can you tell me what it is?
Ans: religious persecution

I know that the answer to the question "Which of the following is not a type of momemtum: angular, curvature or linear?" is in "Mach argued that, in effect, the water experiment in an otherwise empty universe would remain flat. But if another object were introduced into this universe, perhaps a distant star, there would now be something relative to which the bucket could be seen as rotating. The water inside the bucket could possibly have a slight curve. To account for the curve that we observe, an increase in the number of objects in the universe also increases the curvature in the water. Mach argued that the momentum of an object, whether angular or linear, exists as a result of the sum of the effects of other objects in the universe (Mach's Principle).". Can you tell me what it is?

Ans: curvature
